Determine whether or not the function is linear. If it is, determine the slope and interpret it.
-The value of a particular car is given by V(t) $V ( t ) = 22,000 - 3200 t$ t, where t is the age of the car in years.
A) Linear; 3200; Each year, the car depreciates $3200.
B) Not linear
C) Linear; 3200; Each year, the car appreciates $3200.
D) Linear; 22,000; Each year, the car depreciates $22,000.

The function $V(t) = 22,000 - 3200t$ is linear because it can be written in the form $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. The slope is -3200, which means the car depreciates by $3200 each year.

Determine Whether or Not the Function Is Linear V(t)=22,000−3200tV ( t ) = 22,000 - 3200 tV(t)=22,000−3200t
